Mike, I've checked the Wolfe County marriage registry and,
interestingly, there are 2 DÉLIA PINARD. The one, who married Georgina COUTURE has ANTOINE PINARD+Joséphine ROBITAILLE as parents. The other married Marie BEAUDOIN in 1926 and has ÉTIENNE+Joséphine ROBITAILLE as parents.
Neither ANTOINE nor ÉTIENNE marriages are listed under PINARD.
On the other hand, ANTOINE & ÉTIENNE may be the same person, who used both names. He may have been baptized ANTOINE-ÉTIENNE, taking his dad's name for awhile.
In the COUTURE listings, there is a GEORGINA (Bénoni COUTURE+Marguerite COULOMBE), m. 1883.10.01 in Saint-Camille-de-Wotton, QC, to Délia PINARD (ANTOINE PINARD+JOSÉPHINE ROBITAILLE).
In the ROBITAILLE listings, there is a JOSÉPHINE (François-Xavier ROBITAILLE+Marie GIROUX), m. 1857.09.01 in Wotton, QC, to ÉTIENNE PINARD (ANTOINE PINARD+MARIE STCYRR).
There is no mention that JOSÉPHINE ROBITAILLE had 2 marriages in that she could have married the father & then the son, so we may presume her husband was ANTOINE-ÉTIENNE, who used both names.
Whatever, there are children listed for this couple. I'll include the name the father's name in parenthesis:
1) Arsène PINARD (ÉTIENNE+JR), m. 1902.06.02 in Saint-Camille-de-Wotton, QC, to Corona CHARLAND (Édouard+Claire LÉVESQUE);
2) Délia PINARD (ANTOINE+JR) m. 1883.10.10 in Saint-Camille-de-Wotton, QC, to Georgina COUTURE (Bénoni+Marguerite COULOMBE from Ham-Sud);
3) Délia PINARD (ÉTIENNE+JR) m. 1926.07.07 in Wotton, QC, to Marie BEAUDOIN, widow of Joseph CHRÉTIEN;
4) Edmond PINARD (ANTOINE+JR) m. 1886.01.11 in Ham Sud to Marie FORGUES (André+Marie DEVIN);
5) Elmina PINARD (ANTOINE+JR) m. 1897.11.23 in Saint-Camille-de-Wotton, QC, to Gilbert CHARLAND (Édouard+Claire LÉVESQUE);

I copied this info from the 1998 edition of the Wolfe County marriages compiled by La Société de généalogie des Cantons de l'Est.
Hope it helps you out.
